=(2-1)(2+1)*(2^2+1)*(2^4+1)*(2^8+1)*(2^16+1)*(2^32+1)
=(2^2-1)*(2^2+1)*(2^4+1)*(2^8+1)*(2^16+1)*(2^32+1)
=(2^4-1)*(2^4+1)*(2^8+1)*(2^16+1)*(2^32+1)
=(2^8-1)*(2^8+1)*(2^16+1)*(2^32+1)
=(2^16-1)*(2^16+1)*(2^32+1)
=(2^32-1)*(2^32+1)
=2^64-1
=(2^2-1)*(2^2+1)*(2^4+1)*(2^8+1)*(2^16+1)*(2^32+1)
=(2^4-1)*(2^4+1)*(2^8+1)*(2^16+1)*(2^32+1)
=(2^8-1)*(2^8+1)*(2^16+1)*(2^32+1)
=(2^16-1)*(2^16+1)*(2^32+1)
=(2^32-1)*(2^32+1)
=2^64-1
